Wash the potatoes and remove any bad bits (leaving the skin on). Slice them into 1cm thick rounds. Preheat the oven to 200 degrees.
Boil the potaotes for 10 minutes and then drain. Brush 2 tablespoons of olive oil on a baking tray and sprinkle with salt. Place the potatoes on the tray in a flat layer. Brush the tops with olive oil and sprinkle with more salt. Put in the oven for 25 minutes until they start to crisp.
